摘要

AIM:To identify patients' characteristics associated with double balloon endoscopy(DBE)outcomes in investigation of obscure gastrointestinal bleeding(OGIB).METHODS:Retrospective study performed at an academic tertiary referral center.Evaluated endpoints were clinical factors associated with no diagnostic yield or non-therapeutic intervention of DBE performed for OGIB evaluation.RESULTS:We included fifty-five DBE between August 2010 and April 2012.The mean age of the sample was 67 with 32 males(58.2%).Twenty-four DBE had no diagnostic yield and 30 DBE did not require therapy.Non-diagnostic yield was associated with performing two or more DBE studies in one day [odds ratio(OR):13.72,P=0.008],absence of blood transfusions within a year of the DBE(OR:7.16,P=0.03)and absence of ulcers or arteriovenous malformations(AVMs)on prior esophagogastroduodenoscopy(EGD)or colonoscopy(OR:19.30,P=0.033).Non-therapeutic DBE was associated with performing two or more DBE per day(OR:18.579,P=0.007),gastrointestinal bleeding episode within a week of the DBE(OR:11.48,P=0.003),fewer blood transfusion requirements prior to DBE(OR:4.55,P=0.036)and absence of ulcers or AVMs on prior EGD or colonoscopy(OR:8.47,P=0.027).CONCLUSION:Predictors of DBE yield and therapeutic intervention on DBE include blood transfusion requirements,previous endoscopic findings and possibly endoscopist fatigue.
